Alcohol use is associated with hepatic steatosis, even after exclusion of heavy drinkers. Binge drinking was associated with a particularly high risk. The results are drawn from a retrospective analysis of the Framingham Heart Study and indicate a possible connection between alcohol use and nonalcoholic fatty liver disease (NAFLD). If confirmed prospectively, the results suggest that alcohol use could be a target for prevention and treatment of presumed NAFLD.

The study was led by Michelle Long, MD, of Boston University, and was published in Clinical Gastroenterology and Hepatology.

Previous studies have produced mixed results with respect to alcohol consumption and NAFLD, with some reporting increased risk with alcohol consumption, and some a beneficial effect of moderate alcohol consumption. Most such studies focused on average daily or weekly alcohol intake, without examining individual differences in alcohol use behavior.

The current work included 2,475 participants from the Offspring and Third Generation Cohorts of the multidetector CT (MDCT) substudy of the Framingham Heart Study. The researchers excluded heavy drinkers, defined as those who had more than 21 drinks (men) or 14 drinks (women) per week.

Of the sample, 17.3% had hepatic steatosis as measured by MDCT. The risk of hepatic steatosis increased from 15.3% to 54.3% along increasing categories of alcohol use.

With each standard deviation increase in the number of alcohol drinks per week, the risk of hepatic steatosis increased by 15% (adjusted odds ratio, 1.15; 95% CI, 1.02-1.29). Of subjects with presumed NAFLD, 25.4% were binge drinkers, defined as four or more drinks per day in women and five or more in men.

A pattern of risky weekly drinking – defined as 8 or more drinks for women or 15 or more for men – was associated with a 45% increase in odds of hepatic steatosis (aOR, 1.45; 95% CI, 1.06-1.98).

An analysis of only current drinkers showed stronger associations between hepatic steatosis and the number of alcoholic drinks per week, risky weekly drinking, and maximum number of drinks in 24 hours.

When the researchers broke down the analysis by beer, wine, or spirit drinkers, they only found a statistically significant association between alcohol consumption and hepatic steatosis in beer drinkers.

The study authors received funding from a range of nonindustry sources. They reported having no relevant financial disclosures.

Among women with a history of gestational diabetes, a longer period of breastfeeding was associated with a lower probability of going on to develop type 2 diabetes, as well as a more favorable glucose metabolic biomarker profile. Women who breastfed for 2 years or longer had a 27% lower risk than that of those who did not breastfeed at all, even after adjustment for age, ethnicity, family history of diabetes, parity, age at first birth, smoking, diet quality, physical activity, and prepregnancy body mass index, according to findings published in Diabetes Care.

It remains to be seen if the association is causal, and if so, what mechanisms might connect breastfeeding duration to risk for type 2 diabetes, wrote study leaders Sylvia Ley, PhD, of Tulane University School of Public Health and Tropical Medicine, New Orleans, and the Harvard T.H. Chan School of Public Health, Boston, and Cuilin Zhang, MD, PhD, of the Division of Intramural Population Health Research, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Md., and colleagues.

“It’s really nice to see this consistency and the long-term association being borne out in a very large sample of women with gestational diabetes,” Erica P. Gunderson, PhD, said in an interview about the study. Dr. Gunderson has conducted similar studies of her own, including one published in 2018 that showed an independent association between lactation and reduced diabetes risk in women (JAMA Intern Med. 2018;178:328-37). That analysis showed no sign that the presence of gestational diabetes affected the reduction of diabetes risk associated with lactation.

Dr. Gunderson noted that pregnancy is a hyperlipidemic state, with triglyceride levels sometimes doubling, likely in response to the need to support the placenta and the growing fetus. Lactation may help restore lipid levels to the prepregnancy state by redirecting lipids to breast milk. She and others are working to produce more direct evidence of metabolic changes in the postpartum period associated with lactation. “That’s where we don’t have much mechanistic evidence right now,” said Dr. Gunderson, a senior research scientist and epidemiologist at Kaiser Permanente Northern California, Oakland.

Gestational diabetes occurs in an estimated 5%-9% of pregnancies in the United States, and women who experience this complication are at greater risk of developing type 2 diabetes in the future. Findings from other studies have shown that longer lactation periods are associated with lowered risk of future type 2 disease (JAMA. 2005;294:2601-10).

In the latest study, the researchers included 4,372 women with a history of gestational diabetes, identified through the Nurses’ Health Study II. Participants were excluded if they had a history of cancer, cardiovascular disease, or multiple-birth pregnancy before the pregnancy during which they were diagnosed with gestational diabetes. In all, 873 women developed type 2 diabetes over 87,411 person-years of follow-up. The median age at gestational diabetes diagnosis was 31.8 years, and 49.8 years for diagnoses of type 2 diabetes.

After adjustment, the researchers found a steadying decline of risk for type 2 diabetes with increasing length of lactation: for up to 6 months of lactation, the hazard ratio was 1.05 (95% confidence interval, 0.82-1.34); for 6-12 months, the HR was 0.91 (95% CI, 0.71-1.15); 12-24 months, 0.84 (95% CI, 0.67-1.06); more than 24 months, 0.73 (95% CI, 0.57-0.93; P for trend = .004). Age, parity, primipara, prepregnancy body mass index, and age had no statistically significant effect modification on the association.

At a follow-up blood collection taken at median age of 58.2 years and 26.3 years after the gestational-diabetes index pregnancy, the researchers found associations between longer breastfeeding (greater than 24 months vs. 0 months) and lower hemoglobin A_1c percentage (5.58 vs. 5.68; P for trend = .04), lower insulin levels (53.1 vs. 64.7 pmol/L; P for trend = .02), and lower C-peptide levels (3.42 vs. 3.88 ng/mL; P for trend = .02).

The study was supported by the National Institutes of Health. Dr. Ley was supported by a National Institute of General Medical Sciences grant from the NIH. None of the study authors reported any conflicts of interest, and neither did Dr. Gunderson.

A network meta-analysis of migraine treatments in children found little evidence that prophylactic medicines work in this population.

Clinicians hoped that medications used in adults – such as antidepressants, antiepileptics, antihypertensive agents, calcium channel blockers, and food supplements – would find similar success in children. Unfortunately, researchers found only short-term signs of efficacy over placebo, with no benefit lasting more than 6 months.

The study, conducted by a team led by Cosima Locher, PhD, of Boston Children’s Hospital, included 23 double-blind, randomized, controlled trials with a total of 2,217 patients; the mean age was 11 years. They compared 12 pharmacologic agents with each other or with placebo in the study, published online in JAMA Pediatrics.

In a main efficacy analysis that included 19 studies, only two treatments outperformed placebo: propranolol (standardized mean difference, 0.60; 95% confidence interval, 0.03-1.17) and topiramate (SMD, 0.59; 95% CI, 0.03-1.15). There were no statistically significant between-treatment differences.

The results had an overall low to moderate certainty.

When propranolol was compared to placebo, the 95% prediction interval (–0.62 to 1.82) was wider than the significant confidence interval (0.03-1.17), and comprised both beneficial and detrimental effects. A similar result was found with topiramate, with a prediction interval of –0.62 to 1.80 extending into nonsignificant effects (95% CI, 0.03-1.15). In both cases, significant effects were found only when the prediction interval was 70%.

In a long-term analysis (greater than 6 months), no treatment outperformed placebo.

The treatments generally were acceptable. The researchers found no significant difference in tolerability between any of the treatments and each other or placebo. Safety data analyzed from 13 trials revealed no significant differences between treatments and placebo.

“Because specific effects of drugs are associated with the size of the placebo effect, the lack of drug efficacy in our NMA [network meta-analysis] could be owing to a comparatively high placebo effect in children. In fact, there is indirect evidence [from other studies] that the placebo effect is more pronounced in children and adolescents than in adults,” Dr. Locher and associates said. They suggested that studies were needed to quantify the placebo effect in pediatric migraine, and if it was large, to develop innovative therapies making use of this.

The findings should lead to some changes in practice, Boris Zernikow, MD, PhD, of Children’s and Adolescents’ Hospital Datteln (Germany) wrote in an accompanying editorial.

Pharmacological prophylactic treatment of childhood migraine should be an exception rather than the rule, and nonpharmacologic approaches should be emphasized, particularly because the placebo effect is magnified in children, he said.

Many who suffer migraines in childhood will continue to be affected in adulthood, so pediatric intervention is a good opportunity to instill effective strategies. These include: using abortive medication early in an attack and using antimigraine medications for only that specific type of headache; engaging in physical activity to reduce migraine attacks; getting sufficient sleep; and learning relaxation and other psychological approaches to counter migraines.

Dr. Zernikow had no relevant financial disclosures. One study author received grants from Amgen and other support from Grunenthal and Akelos. The study received funding from the Sara Page Mayo Endowment for Pediatric Pain Research, Education, and Treatment; the Swiss National Science Foundation; the Schweizer-Arau-Foundation; and the Theophrastus Foundation.

The severity of Sjögren’s syndrome and its organ involvement has direct links to clinical characteristics that include age, gender, ethnicity, and geographical location, according to new research findings from a large, worldwide database of primary Sjögren’s syndrome patients.

Risk factors for more severe disease included male sex, earlier age at diagnosis, black/African-American (BAA) ethnicity, and living in more southerly countries, including below the equator. The authors hailed these factors as potentially helping to predict the presence of systemic disease in newly-diagnosed patients, as well as helping to determine the optimum follow-up strategy.

But not everyone agrees. In interviews, other experts suggested that the data were interesting and valuable, but were not ready to make reliable clinical predictions. “The predictive value of these data are limited when it comes to an individual patient sitting in front of you in the office,” said Tomas Mustelin, MD, professor of medicine at the University of Washington, Seattle.

“It would be an important clinical thing if you can figure out who’s at risk for systemic complications and who isn’t. This is a nice step in that direction,” said Hal Scofield, MD, professor of medicine and pathology at the University of Oklahoma, Oklahoma City, agreeing that the data were too preliminary to be broadly useful because there is too much overlap between different patient groups.

If there is one clinical message, it is that physicians should be looking beyond dry eyes and dry mouth in newly diagnosed Sjögren’s syndrome, according to Sarah Chung, MD, who is an acting instructor of rheumatology at the University of Washington. “It’s a reminder to investigate these extra-glandular manifestations, and a reminder that it is a heterogeneous presentation, so we have to keep an open mind and investigate thoroughly,” she said.

In the research published online in Rheumatology, first author Pilar Brito-Zerón, MD, PhD, of the University of Barcelona Hospital Clínic, and colleagues in the Sjögren Big Data Consortium used European League Against Rheumatism Sjögren’s syndrome disease activity index (ESSDAI) scores to examine phenotype and patient characteristics among 10,007 subjects drawn from the international consortium.

Overall, 93.5% of subjects were women, and the mean age at diagnosis was 53 (standard deviation [SD], 14.1 years). The mean total ESSDAI score was 6.1 (SD, 7.5).

Men had higher mean ESSDAI (8.1 vs. 6.0; P less than .001) and clinical ESSDAI (8.4 vs. 6.1; P less than .001) scores and were more likely to have a high disease activity state (22.5% vs. 11.7%; P less than .001). Domains that scored higher in men included lymphadenopathy (P less than .001), glandular (P less than .001), pulmonary (P = .001), peripheral nervous system (PNS) (P less than .001), and CNS (P less than .001).

The highest global ESSDAI scores were reported in patients younger than 35, but organ dominance differed by age group: The constitutional, lymphadenopathy, glandular, cutaneous, renal, hematologic, and biologic domains were highest in this age group, but pulmonary and peripheral nervous system were highest in patients over 65.

By ethnicity, the highest ESSDAI scores occurred in black/African-American patients (6.7), followed by white (6.5), Asian (5.4), and Hispanic (4.8; P less than .001). The organ-specific domains also tracked by ethnicity, with BAA patients experiencing the highest frequencies of activity in the lymphadenopathy, articular, neurologic, and biologic domains. White patients were more often affected in the glandular, cutaneous, and muscular domains, whereas Asians most often experienced the pulmonary, renal, and hematologic domains, and Hispanics the constitutional domain.

The survey included Europe, America, and Asia, and global ESSDAI scores were higher in the southern countries of Asia and Europe, and higher in countries below the equator in the Americas. The organ-by-organ activity scores had a differentiated pattern between northern and southern locales. Worldwide, the gradient of patients with moderate systemic activity (global ESSDAI score of 5 or higher) at diagnosis followed a north-south gradient.

The study had no specific funding, and the authors have no relevant financial disclosures. Dr. Mustelin, Dr. Scofield, and Dr. Chung have no relevant financial disclosures.

The severity of Sjögren’s syndrome and its organ involvement has direct links to clinical characteristics that include age, gender, ethnicity, and geographical location, according to new research findings from a large, worldwide database of primary Sjögren’s syndrome patients.

Risk factors for more severe disease included male sex, earlier age at diagnosis, black/African-American (BAA) ethnicity, and living in more southerly countries, including below the equator. The authors hailed these factors as potentially helping to predict the presence of systemic disease in newly-diagnosed patients, as well as helping to determine the optimum follow-up strategy.

A study using a new definition of early chronic obstructive pulmonary disease (COPD) has found that about 15% of Danish smokers under the age of 50 years meet the criteria.

The population-based cohort looked at individuals who had been exposed to at least 10 pack-years, and defined early COPD as the ratio of forced expiratory volume to forced vital capacity being less than the lower limit of normal (FEV₁/FVC less than LLN). The definition of early COPD, published in 2018 (Am J Resp and Crit Care Med. 2018;197:1540-51), also included the presence of abnormalities on a CT scan or a decline in FEV₁ (greater than 60 mL/year) that is accelerated relative to FVC, but the new population study did not include the latter two criteria.

The researchers, under corresponding author Peter Lange, MD, of the University of Copenhagen found that those with early COPD were more likely to have chronic respiratory symptoms, severe impairment of lung function, acute respirator hospitalization, and early mortality at baseline and at follow-up. The work was published in the American Journal of Respiratory and Critical Care Medicine.

“To dig through the smokers and try to figure out which smokers are more at risk than other smokers is probably the best way to summarize what they’ve done here,” said Robert Reed, MD, from the University of Maryland, Baltimore, in an interview. However, he added that he would like to see the research extended to an even younger population, as well as nonsmokers. “We don’t need all of this information to tell us that smoking is bad. I think nonsmokers would be really interesting – creating a definition of COPD that excludes patients that meet the usual definition for COPD would be of potential interest,” added Dr. Reed, who was not involved in the study.

Using a cohort of 105,630 randomly selected individuals from Danish nationwide health registries, the study identified 8,064 individuals aged under 50 years with 10 or more pack-years of tobacco exposure. In this group, 1,175 (15%) had early COPD, of whom 58% were current smokers. The cohort of smokers was followed for up to 14.4 years. Multivariate analyses found that those with early COPD, compared with smokers without COPD, were at substantially greater risk of acute obstructive lung disease hospitalization (hazard ratio, 6.42; 95% confidence interval, 3.39-12.2), acute pneumonia hospitalization (HR, 2.03; 95% CI, 1.43-2.88), and all-cause mortality (HR, 1.79; 95% CI, 1.28-2.52).

There is value in gaining a better understanding of which smokers are at greatest risk of COPD down the line, but data on younger people, even 30-year-olds, could guide therapeutic decisions when and if new drugs that can alter the state of the disease become available. Focusing more on younger, high-risk patients could also be used to create greater incentives to quit smoking, though Dr. Reed has mixed feelings even about that. “What if we identified 15% of smokers that are at risk of COPD, and the other 85% say, ‘I’ll keep smoking,’ and they fall over dead from a heart attack?” said Dr. Reed, noting that smoking has a wide range of known risks. “They should all stop,” he added.

The study also captures a wide range of patients, from some with early disease that will likely progress to COPD later in life along with some who already developed full-blown COPD in, for example, their early 40s. “Those are very different patients and to lump them together is potentially problematic,” said Dr. Reed. More granulated data could potentially inform more personalized medicine, and the discovery and verification of genetic risk factors.

Nevertheless, Dr. Reed expects the data to move the field forward. “They created a nice, rich database that I think will generate a lot more analysis and discussion.”

The study was funded by the Lundbeck Foundation. One of the authors has received support from the National Institute for Health Research Manchester (England) Biomedical Research Centre. Dr. Reed has no relevant financial disclosures.

Treatment with sodium zirconium cyclosilicate (SZC) led to lasting improvement of hyperkalemia, according to results from an 11-month open-label extension study of the HARMONIZE randomized clinical trial.

SZC selectively binds potassium ions in the colon, reducing absorption and promoting excretion. In the original study, 248 patients with mild hyperkalemia were randomized to SZC or placebo. Within 48 hours, the drug returned potassium to normal and maintained those levels out to 4 weeks.

In the extension study, 123 patients with measured potassium levels of 3.5-6.2 mmol/L, 48 of whom had previously been assigned to placebo, received a 5- to 10-g dose of SZC once per day for up to 337 days. Median daily dose was 10 g, with a dose range of 2.5-15 g (Am J Nephrol. 2019;50[6]:473-480).

Just under 65% of patients completed the 11 months of the open-label extension study, with 88.3% of those achieving the primary endpoint of mean serum potassium levels of 5.1 mmol/L or lower, according to Simon D. Roger, MD, a nephrologist based in Gosford, Australia, and colleagues.

Most patients (83) were taking renin–angiotensin–aldosterone system inhibitors at baseline of the extension study; 78.3% continued a stable dose throughout the open-label phase, 8.4% increased the dose, and 3.6% discontinued.

Two-thirds of patients reported adverse events, most commonly gastrointestinal disorders (18.7%). Constipation was the most frequent (5.7%), followed by nausea, vomiting, and diarrhea (3.3% each).

Adverse events that occurred in 5% or more of participants included hypertension (12.2%), urinary tract infection (8.9%), and peripheral edema (8.1%). Hypertension severity was either mild (46.7%) or moderate (53.3%), and only one case was believed to be associated with the study medication. Thirteen percent of participants reported a total of 17 SMQ edema events. Eleven of the 16 patients had baseline risk factors for edema, leading the authors to conclude that causality between SZC and edema could not be established.

Serious adverse events occurred in 19.5% of participants, and 4.9% of participants discontinued SZC as a result.

SZC is approved for the treatment of hyperkalemia in the United States and Europe. The study was funded by AstraZeneca.

More than half of patients who undergo prolonged mechanical ventilation experience an acute laryngeal injury (ALgI), and the injury is associated with worse breathing and speaking at 10 weeks, according to a study published in Critical Care Medicine (2019 Dec;47[12]:1669-1706). The researchers, led by Alexander Gelbard, MD, of Vanderbilt Medical Center, Nashville, Tenn., found that higher body mass index, diabetes, and larger endotracheal tube (ETT) size were all associated with heightened risk.

The investigators assert that comparatively scarce data are available about how patients fare after receiving mechanical ventilation, and how adverse effects might interfere with recovery and return to daily activity. The larynx is rarely examined after extubation, and laryngeal injury may initially appear to be minor. Restricted glottic mobility therefore tends to be diagnosed after discharge, leaving critical care specialists unaware of the long-term impact.

The findings of the study should be a wake-up call for the development of guidelines for recognition and management of laryngeal injuries, according to John Robert Gowardman, MD, of Royal Brisbane (Australia) and Women’s Hospital, who wrote an accompanying editorial (Crit Care Med, 2019 Dec;47[12]:1802-04).

In addition, findings that ETT size, diabetes, and BMI represent risk factors for injury should help identify patients at risk, and the “practice of ‘putting in the biggest ETT just in case’ needs to be balanced against the dangers of an undersized ETT ... we should ask, ‘can my patient be safely managed with a smaller ETT?’ ” wrote Dr. Gowardman.

The researchers followed 100 consecutive adult patients who were examined with nasolaryngoscopy following an intubation of greater than 12 hours at Vanderbilt University Medical Center. They recorded baseline comorbidities and other factors. Fifty seven patients had an ALgI, defined as having glottic mucosal ulceration/granulation or subglottic granulation tissue/stenosis at the time of endoscopy. Nineteen patients had granulation tissue, 48 had posterior glottic ulceration, and 8 had subglottic mucosal ulceration.

Ten weeks after extubation, all patients were contacted by phone and asked to answer the Voice Handicap Index (VHI)-10 and the Clinical Chronic Obstructive Pulmonary Disease Questionnaire (CCQ). The questioner did not know the results of the patient’s endoscopy. Patients with ALgI were heavier on average (mean difference, 14 kg; BMI difference, 3.8 kg/m²), were more likely to have type 2 diabetes (46% versus 21%), and had more severe illness (median Charlson Comorbidity Index, 3.00 versus 2.00).

Sixty-seven patients completed the 10-week questionnaires, including 40 patients with ALgI and 27 without ALgI. Injury was associated with reports of worse breathing (median CCQ, 1.05 versus 0.20; P less than .001), as well as worse patient-reported voice outcomes (median VHI, 2 versus 0; P = .005).

ETT size appeared to be an important factor, according to multivariate analyses. Use of a 7.0 ETT was associated with lower frequency of injury than 7.5 (adjusted odds ratio, 0.04; P = .004) and 8.0 (OR, 0.03; P = .004). There was no significant difference between the 7.5 and 8.0 sizes.

The presence of type 2 diabetes altered the risk associated with BMI (P = .003 for interaction). Among patients who did not have type 2 diabetes, ALgI went up as a function of increasing BMI. Still, injury risk was higher in the presence of type 2 diabetes across all BMI ranges.

More than half of patients who undergo prolonged mechanical ventilation experience an acute laryngeal injury (ALgI), and the injury is associated with worse breathing and speaking at 10 weeks, according to a study published in Critical Care Medicine (2019 Dec;47[12]:1669-1706). The researchers, led by Alexander Gelbard, MD, of Vanderbilt Medical Center, Nashville, Tenn., found that higher body mass index, diabetes, and larger endotracheal tube (ETT) size were all associated with heightened risk.

The investigators assert that comparatively scarce data are available about how patients fare after receiving mechanical ventilation, and how adverse effects might interfere with recovery and return to daily activity. The larynx is rarely examined after extubation, and laryngeal injury may initially appear to be minor. Restricted glottic mobility therefore tends to be diagnosed after discharge, leaving critical care specialists unaware of the long-term impact.

VANCOUVER – A retrospective analysis of women who became pregnant after undergoing laparoscopic radiofrequency ablation (Lap-RFA) of symptomatic myomas found no evidence that the procedure negatively impacted pregnancy or birth outcomes, according to Jay Berman, MD.

The procedure is a minimally invasive alternative to myomectomy, hysterectomy, and other surgical techniques, with minimal scarring and quick recovery. But the pivotal trials excluded women who were planning to become pregnant, and the Food and Drug Administration recommends against its use in women planning a future pregnancy because of the lack of safety and efficacy data in that population.

The procedure, which gained FDA approval in 2016, combines laparoscopic ultrasound with targeted radiofrequency to heat fibroids, which then shrink over the next few months. “There have been a lot of questions from infertility specialists regarding whether Lap-RFA can be applied to their patients because there’s very little scarring and a quick return to work. It’s really a very nice outpatient procedure for dealing with fibroids,” Dr. Berman said in an interview.

There is natural concern, however, because clinicians are uncomfortable exposing women to a pregnancy risk. “I think there’s concern from many gynecologists and reproductive endocrinologists on the pregnancy outcomes following fibroid therapy, whatever that happens to be – traditional open laparoscopic myomectomy, robotic myomectomy, all of those kinds of therapies. We were interested in looking at pregnancy outcomes following [RFA for fibroids] and whether or not C-sections would need to be recommended, similar to what you see following myomectomy, where if you enter the cavity or go through more than half of the myometrium, you recommend a C-section for that patient in subsequent pregnancies,” said Dr. Berman, who is a professor of obstetrics and gynecology at Wayne State University, Detroit.

Early case studies, mostly done in Mexico and Guatemala, found the uteri of women to be normal following Lap-RFA, he said.

The results of this study are encouraging, but are far from the final word, as the data are retrospective and small. Acessa, which provided statistical analysis for the current work, is planning a prospective study. “I don’t think there’s enough to say that the labeling should be changed, but we’re moving in that direction. There needs to be a lot more information,” Dr. Berman said at the meeting sponsored by AAGL.

The study combined data from two randomized, controlled trials in the United States and Germany; six cohort studies in the United States, Germany, and Latin America; and commercial procedures performed in the United States. The researchers relied on standardized case reports that focused primarily on maternal and infant safety, and the mode of delivery. They collected data from 38 women (mean age, 36 years) who had fibroids types 1-6 that were of a maximum 0.2-13 cm in diameter. In 19 cases, it was 5.5 cm or smaller. The number of fibroids treated ranged from 1 to 31; 19 women had one or two fibroids treated.

There were a total of 43 pregnancies, 32 of which resulted in full-term live births (74%) and there was 1 preterm birth (2.3%). All infants were healthy, and there 19 vaginal births and 13 C-sections. The reasons for the C-sections were previous C-sections or obstetric indications, such as unusual bleeding, nonprogression of labor, or abnormal fetal heartbeat. There were eight spontaneous abortions (19%) and one therapeutic abortion (2.3%), and one pregnancy was ongoing (2.3%).

Dr. Berman has been a consultant for Acessa Health, Bayer, Boston Scientific, Medtronic, and Abbvie. He has been on the speakers bureau for Acessa, Merck, Boston Scientific, Medtronic, Abbvie, and Lupin. He has performed contracted research for Acessa, Bayer, Allergan, and Obseva.

VANCOUVER, B.C. – Marijuana and cannabidiol (CBD) use is quite common among patients with pelvic pain resulting from endometriosis, with over a third reporting either current or past use, according to a new survey.

The finding comes as more and more companies are marketing CBD-containing products to women, with unsubstantiated claims about efficacy, according to Anna Reinert, MD, who presented the research at a meeting sponsored by AAGL.

Women self-reported that marijuana use was moderately effective, while the median value for CBD corresponded to “slightly effective.”

To investigate use patterns, Dr. Reinert and colleagues created a questionnaire with 55-75 questions, which followed a branching logic tree. Topics included pain history, demographics, and experience with marijuana and CBD for the purpose of controlling pelvic pain. The survey was sent to two populations: an endometriosis association mailing list, and patients at a chronic pain center in Phoenix.

About 24,500 surveys were sent out; 366 were received and analyzed. The response rate was much different between the two populations, at 1% in the endometriosis association and 16% of the clinic population. Dr. Reinert attributed the low response rate in the association sample to the continuing stigma surrounding marijuana use, citing much higher response rates to other surveys sent out by the association around the same time.

Overall, 63% of respondents said they had never used marijuana; 37% reported past or present use; 65% said they had never used CBD; and 35% reported past or present use. About 45% of marijuana users reported that its use was very effective, and 25% said it was moderately effective. About 22% of CBD users said it was very effective, and about 33% said it was moderately effective. The median values lay in the moderately effective range for marijuana, and in the slightly effective range for CBD.

The findings suggest a need for more research into the potential benefit and limitations of cannabis for pelvic pain from endometriosis, said Dr. Reinert, an obstetrician/gynecologist the University of Southern California, Los Angeles.

Until this study, evidence of efficacy of marijuana for this indication has been sparse. A report from the National Academy of Sciences showed that there is evidence that cannabis and cannabinoids have a therapeutic effect on chronic pain in adults (National Academies Press (US) 2017 Jan 12), but the report made no mention of gynecological applications. Despite this lack of evidence, surveys have shown that women of reproductive age use marijuana, and an analysis by the Ameritox Laboratory in a pain management population found that 13% of women and 19% of men tested positive for marijuana in their urine.

Still, “there is not research looking at marijuana for women with chronic health pain,” Dr. Reinert said at the meeting.

But that doesn’t stop companies from developing CBD vaginal suppositories and marketing them for menstrual pelvic discomfort, pain during sex, and other issues. Lay press articles often boost these claims, although some skeptical takes address the lack of evidence. Still, “there’s a lot on the more positive side,” she said.

That leads to a lot of interest among patients in using marijuana or CBD for symptom relief, which is part of the reason that Dr. Reinert’s team decided to examine its use and perceived efficacy. Another reason is that there is some biological basis to believe that cannabis could be helpful. There is some evidence that women with endometriosis have changes in their endocannabinoid system (Cannabis Cannabinoid Res. 2017;2:72-80), and there are clinical trials examining the impact of non-CBD, non-tetrahydrocannabinol (THC) endocannabinoid ligands.

Dr. Reinert has no financial disclosures.

VANCOUVER – Presurgical ultrasound does a good job predicting advanced versus early American Society of Reproductive Medicine endometriosis stage, and that can help ensure that a patient gets to the right surgeon.

Researchers retrospectively collected data from ultrasounds, using it to create an ASRM stage, and compared the results with the stage seen at surgery. “We’re very good at telling people what they should expect at surgery,” said Mathew Leonardi, MD, who is a gynecologist at the University of Sydney’s Nepean Hospital.

The researchers conducted the study because of perceived mistrust among surgeons when it comes to presurgical imaging. “There is still a lot of cynicism and a lot of hesitancy to adopt this,” Dr. Leonardi said at the meeting sponsored by AAGL. He was unapologetic about the activist nature of the research. “We thought, what better way [to convince surgeons] than to produce an ultrasound-based ASRM scoring system to then match to the surgical findings, because if we can predict the ASRM score preoperatively, there may be more buy-in by the surgeons for the value of imaging.”

He noted that surgeons differ in their training, so getting the patient to the right surgeon is critical. “If you go to a gynecologist who is not minimally invasive trained, you may [end up with] an abandoned surgery, or an incomplete surgical excision leading to residual disease. So being able to predict the severity of the disease preoperatively, you can allow the patient to get to the right surgeon with the right team members.”

The analysis included 204 procedures performed between January 2016 and April 2018. Participants underwent deep endometriosis transvaginal ultrasound at one of two tertiary referral service centers, and laparoscopy by surgeons in the Sydney metropolitan area. Each case was received as a ASRM score of 0-4 at both ultrasound and surgery, and scores of 0-2 and 3-4 were grouped together for analysis.

“We grouped patients that have ASRM 3-4 into one group and those who have less than that [into another group], because clinically that seems to be where the most practical divide is,” said Dr. Leonardi.

It was difficult to differentiate individual ASRM stages from one another using ultrasound, but the technique performed much better in the combined analysis. In assigning a patient to the ASRM stage 0-2 endometriosis group, it had 94.9% sensitivity and 93.8% specificity, and for assigning to ASRM stage 3-4, it had values of 93.8% and 94.9%, respectively.

The success is encouraging, but there is more work to be done. “We are going to have to differentiate those with early-stage endometriosis or stage 1-2, and those that are negative. We are working on being able to identify superficial endometriosis noninvasively, but for now, as a triaging tool ultrasound can get the patient to the right surgeon,” Dr. Leonardi said.

VANCOUVER – Presurgical ultrasound does a good job predicting advanced versus early American Society of Reproductive Medicine endometriosis stage, and that can help ensure that a patient gets to the right surgeon.

Researchers retrospectively collected data from ultrasounds, using it to create an ASRM stage, and compared the results with the stage seen at surgery. “We’re very good at telling people what they should expect at surgery,” said Mathew Leonardi, MD, who is a gynecologist at the University of Sydney’s Nepean Hospital.

The researchers conducted the study because of perceived mistrust among surgeons when it comes to presurgical imaging. “There is still a lot of cynicism and a lot of hesitancy to adopt this,” Dr. Leonardi said at the meeting sponsored by AAGL. He was unapologetic about the activist nature of the research. “We thought, what better way [to convince surgeons] than to produce an ultrasound-based ASRM scoring system to then match to the surgical findings, because if we can predict the ASRM score preoperatively, there may be more buy-in by the surgeons for the value of imaging.”

He noted that surgeons differ in their training, so getting the patient to the right surgeon is critical. “If you go to a gynecologist who is not minimally invasive trained, you may [end up with] an abandoned surgery, or an incomplete surgical excision leading to residual disease. So being able to predict the severity of the disease preoperatively, you can allow the patient to get to the right surgeon with the right team members.”
